Question

define potential energy. derive it's formula​

Answer 1

Potential energy

the energy possessed by a body at rest due to its position or size and shape is called potential energy .

U= mgh

Explanation:

Potential energy derivation

Potential energy is the work done to take a body to a certain height. For a body with mass m, h is the distance to which it is raised and g is the gravitational force acting on the body, then work done W is given as:

W = force displacement

W = mg h

∴ W = mgh

As the work done is equal to mgh which is gained by the object, potential energy Ep is given as:

Ep = mgh

Therefore, above is the derivation of potential energy.
